`CAR-TRUCK.

PECFICATION forming part of Letters Patent No. 714,673, dated December 2, 1902.

Application filed May 1, 1902. Serial No. 105,447. (No model.)

To a/ZZ whom t may concern:

Be it known that I, EDWARD CLIEE, a citiz'en of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Car-Trucks, of "which the following is a specification.

The invention relates to improvements in car-trucks; and it consists in the novel features and combinations of parts hereinafter described, and particularly pointed out in the claims. p

The object of the. invention is to simplify and render more durable and efiicientcartruck frames; and the said invention pertains more particularly to the side and pedestal frames of the truck.

In carrying out my invention I construct the side frames of the truck from rolled I- beams cut off at suitable lengths and equipped with pedestal-frames for the axle-boxes, and also with suitable springs above the axleboxes and bearing on thesameat opposite sides of the vertical plane of the web of the side frames.

' The truck-frame constructed in accordance with my invention is one of great durability and efficiency and capable of being manufactured without undue expense.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which- Figure 1 is a topview of a portion of a truck-frame constructed in accordance with and embodying the invention. Fig. 2 is a side elevation of same, the car-axles being in section. Fig. 3 is an enlarged side elevation, partly in section, of one end of the truckframe. Fig. 4 is an end view, partly broken away, of the end of the truck-frame; and Figs. 5 and@ illustrate a modiied form of the invention,`Fig. 5 being an end view, partly broken away, of one end ofthe side frame, and Fig. 6 being a side elevation of an end portion of the sideframe, these figures disclosing a suitable form of pedestal-frame for use when coiled springs are employed over the axle-boxes in lieu of the ellipticsprings illustrated in Figs. '1 to 4, inclusive.

In the drawings I illustrate as much of an electric or passenger car truck as is suiiicient In the drawings, 10 designate the beam side frames; 11, the truck-wheels; 12, customary journal-boxes for the car-.axles 13, and 14 the springs, bearing upon the upper Vends of said journal-boxes and confined at their upper ends below the upper laterallyprojecting iianges 15 of the beam side frames.

The beam side frames l0 will be connected at their middle portions by means of a suitable transom-beam 16 16 and at their ends by suitable connecting rods or bars 17, said transom and said end bars or rods being of `any suitable form or construction and not being specifically claimedherein, since the present invention pertains more especially to the beam side frames and their parts, without regard to the special means employed for connecting vtogether the two side frames of the truck. y The side frames of the truck are each constructed from a rolled I-beam having the vertical web portion 18, the aforesaid laterally-projecting flange 15 along the upper edge of said web portion, and the corresponding lower flange 19, said flanges 15 and 19 projecting laterally both inward and outward from the web portion 18. It is an important feature of the side frames 10 that the upper and lower iianges 15 19 shall project laterally in both directions from the web 18, since thereby a very strong and durable side frame is produced and means are provided for enabling the location of the springs 14 at both sides of each side frame. The side frames 10 are each formed from a rolled I-beam cut out at its opposite ends to form the spaces 2O 20 for the journal-boxes 12, said spaces 2O being cut through the lower iiange 19 and partly through a portion of the web 18, but not through the upper iiange 15, the flange 15 and a part of the web 18 over the spaces 20 beingleft intact. The axle-boxes 12 are partly below the lower ange 19 of the side frames, and the lower portions of said journal-boxes are inclosed on their three sides by the pedestalframes 2l, having the horizontal arms 22, fitting against the lower surface of the liange "19 and rigidly, though detachably, secured thereto by means of bolts 23, which extend IOO through said arms 22 and said ange 19 at both sides of the WeblS of the side frames. The outline defined by the three main sides of the pedestal-frame 21 completes the space for the journal-'boxes 12, and at opposite sides of the journal-boxes 12 are provided the additional pedestal-frame members 24, these members 24 being in the form of triangularof the side frame 10, there being two of said members 24 at the outer side and two at the inner side of each end of the side frame, and the said pedestal-frame members 24 are secured in position by the vertical bolts 23, above referred to, and by the horizontal bolts 28, which extend through the web 27 of said members 24 and also through the web 18 of the side frames. The pedestal-frame members 21 24, when in position, receive between their facing vertical surfaces the journalboxes 12 and permit of the proper vertical motion of the same.

The journal-boxes 12 have upon their upper ends suitable sockets or frames 29 to receive and confine (referring to Figs. 1, 2, 3, and 4) the middle port-ion of the semi-elliptic springs 14, whose ends extend upward and are freely confined within cast sockets 30, se-

cured immediately below the upper iauge 154 of the side frames 10, said sockets 30 fitting against the web 18 and the lower surfaces of the ange 15 at each side of the side frame and being secured by bolts 31 to said web. The sockets 30 are arranged in pairs, one socket being at each side of the web 18 at cach end of the springs 14, and the said sockets 30 are in pairs secured to the web 18 by means of the rivets or bolts 31. There is one semielliptic spring 14 at each side of the web 18 of the side frame, there thus being two of the semi-elliptic springs 14 for each journal-box 12, said springs 14 being set as far as may be below the laterally-projecting portions of the tianges 15 of the side frame. The sockets 30 freely receive the upper ends of the semielliptic springs 14, so that said ends may have a free play therein during the employment of the car-truck. The sockets 30 being in the position described transmit the force exerted by the upper ends of the springs along and through the upper liange 15 of the side frames and at each side of the web 18. The side frame 10 being formed from a rolled I-beam enables me to properly secure the pedestalframe members and the sockets 30 for the springsin an entirely secure and durable manner and also enables me to produce an efticient car-truck frame at comparatively small expense, said frame being enabled to withstand all of the rough usage to which cartruck yframes are ordinarily subjected. It is therefore an important feature of the present invention that the side frames are made from rolled I-beams as distinguished from other forms of known side frames for metal trucks.

The upper and lower laterally-projecting flanges 15 19 of the side frames afford satisfactory opportunity for rigidly securing the ends of the transom -beams 16 to the side frames.

The web portion 18 of the side frames, in view of the I shape of said frames, may be cut out, as at 32, to allow for the projecting ends of the bolster (not shown) and as at 33 for permitting of the inspection of the interior parts of the truck and the convenient manipulation or application of said interior parts. The presence of the upper and lower iianges 15 19, projecting laterally from both sides of the web 18, enable the removal of parts of said web to form the spaces 32 33 without interfering with the proper strength and durability of the side frames.

In Figs. 5 and 6 I illustrate a modified form of the invention, this modification consisting in an arrangement of the parts suitable for employing coiled springs above the journalboxes in lieu of the elliptic springs shown in Figs. 1 to 4, inclusive. The side frame 10 `(shown in Figs. 5 and 6) is substantially the same as the side frame shown in Figs. 1 to 4, inclusive, the only essential difference between the two side frames being that in Figs. 5 and 6 I illustrate in lieu of the pedestalframe members 24 of Figs. 1 to 4, inclusive,

IOO

pedestal-frame members 40, which extend y.

from the lower ange 19 of the side frames to the upper ange 15 thereof, said pedestalframe members 40 each being in one integral piece and each comprising the web portions 41 at opposite sides of the space for the journal-box,the right-angular Iianges 42,the lower horizontal fianges 43, fitting and secured to the lower flange 19, and the upper sections 44, connecting the upper ends of the webs 41 and fianges 42 and fitting the under side of the upper flange 15 of the side frames, to which said section 44 is secu red by means of the bolts 45. The upper section 44 of the pedestalframe members 40 aords sockets for the upper ends of the coiled springs 46, there being two springs 46 at each side of the side frame and said springs having their lower ends resting and bearing upon the axle-boxes 12. The pedestal-frame member 40 is duplicated at each side of each end of the side frame and is in one integral casting extending around the upper portion of the space 20 for the journal-box and matching the lower pedestal-v frame member 2l, extending around three sides of the journal-box and, with the pedestal-frame member 40, affording the guidingsurfaces for the journal-box. The coiled springs 46 are to as great an extent as possible located below the flange 15 of the side frames, as shown in Fig. 5, in which respect they correspond with the location of the semielliptic springs 14, as shown in Figs. 1 to 4,
